Processed Meats May Cause Manic Episodes

An analysis of more than 1,000 people with and without psychiatric disorders has shown that nitrates — chemicals used to cure meats such as beef jerky, salami, hot dogs and other processed meat snacks — may contribute to mania, an abnormal mood state. Mania is characterized by hyperactivity, euphoria and insomnia. The findings of the Johns Hopkins Medicine study, which was not designed to determine cause and effect, were published July 18 in Molecular Psychiatry. Specifically, it found that people hospitalized for an episode of mania had more than three times the odds of having ever eaten nitrate-cured meats than people without a history of a serious psychiatric disorder. Experiments in rats by the same researchers showed mania-like hyperactivity after just a few weeks on diets with added nitrates. While a number of genetic and other risk factors have been linked to the manic episodes that characterize bipolar disorder and may occur in other psychiatric conditions, those factors have been unable to explain the cause of these mental illnesses, and researchers are increasingly looking for environmental factors, such as diet, that may play a role. Mania, a state of elevated mood, arousal and energy that lasts weeks to months, is generally seen in people with bipolar disorder, but can also occur in those with schizoaffective disorder. Manic states can lead to dangerous risk-taking behavior and can include delusional thinking, and most of those affected experience multiple hospitalizations in the course of their psychiatric illness.
